I’m not getting any output from audio software applications through my Duet 2. What should I check?

1. Verify the unit is properly connected and recognized by the Mac.  You should see 4 icons on Duet's OLED (input 1, input 2, speaker out, headphone out).
2. Select Duet USB as your Mac Sound Output device in System Preferences/Sound or in Audio MIDI Setup (Applications/Utilities).
3. If you have chosen Mixer for the output selection in Apogee Maestro 2 (or Apogee Control 2, depending on which version you installed), then the Software Return fader must be raised to send audio software application outputs to Duet’s outputs.
